Filbert trees that produce no nuts
Hi, We rec'd 4-5 filbert "starts" from neighbors (don't know the variety) whose trees seem fairly productive in general. They are now getting large (8-9 ft tall), but only one of them has produced nuts, and not too many at that. Most are not in the sunniest location; but it's certainly not full shade. Nearby Santiams produce well. They seem healthy and vigorous. What could be going on and what could we try to improve production? Thank you. (I could get photos if need be).

We have not been able to find any hazelnut experts in Washington to respond. Go ahead and call the Skagit County Extension office and they should be able to help you.
